- 'Double-duty' electrolyte enables new chemistry for longer-lived batteries
- Thu, 24 Apr 2014 11:33:11 EDT - Researchers have developed a new and unconventional battery chemistry aimed at producing batteries that last longer than previously thought possible. Researchers have challenged a long-held assumption that a battery's three main components -- the positive cathode, negative anode and ion-conducting electrolyte -- can play only one role in the device.
- Small business owners not always worried about being treated fairly, researcher finds
- Thu, 24 Apr 2014 11:33:09 EDT - Fairness is not always the most important priority for small retailers. In an international study, researchers found that some small retailers are less concerned about whether they are treated fairly by business suppliers than other factors, such as cash flow and company survival. "It is presumed that fairness, however it is defined by individual businesses, is important to all businesses," one researcher said. "Our research challenges that presumption and reveals that the importance placed on fairness can vary greatly among retailers."
- The blood preserved in the preserved relic pumpkin did not belong to Louis XVI
- Thu, 24 Apr 2014 11:33:03 EDT - The results of an international study indicate that the DNA recovered from the inside of a pumpkin, attributed so far to the French King Louis XVI, does not actually belong to the monarch, guillotined in 1793. Complete genome sequencing suggests that blood remains correspond to a male with brown eyes, instead of blue as Louis XVI had, and shorter.
- Spiders in space weave a web of scientific inspiration for Spider-Man fans
- Thu, 24 Apr 2014 11:30:40 EDT - While spiders were busy spinning webs in space, researchers on Earth weaved their knowledge of this activity into educational materials to inspire and motivate students. Now, this free, Web-based guide is being re-released through Scholastic and Sony Pictures as curriculum for educators to leap on the excitement surrounding the release of the film, "The Amazing Spider-Man 2."
- 'Tis the season: Be on the lookout for brown recluse spiders
- Thu, 24 Apr 2014 11:27:50 EDT - Warmer, spring weather has many of us getting out and becoming more active, and the brown recluse spider is no exception. Scientists shared 10 facts about the somewhat small, shy spider.
- Paying closer attention to attention
- Thu, 24 Apr 2014 11:27:48 EDT - There may be an overreporting of attention problems in children with fetal alcohol spectrum disorder (FASD), simply because parents and teachers are using a misplaced basis for comparison. They are testing and comparing children with FASD with children of the same physical or chronological age, rather than with children of the same mental age, which is often quite a lot younger.
- Equipped with new sensors, Morpheus preps to tackle landing on its own
- Thu, 24 Apr 2014 11:27:47 EDT - A test flight later this week will challenge a set of sensors to map out a 65-yard square of boulder-sized hazards and pick out a safe place to land. Mounted to an uncrewed prototype lander called Morpheus that flies autonomously several hundred feet above the ground, the sensor system will have 10 seconds to do its work: six seconds really, as it will take four seconds to map the area before choosing a landing site. The sensor system is a 400-pound set of computers and three instruments called ALHAT, short for Autonomous Landing and Hazard Avoidance Technology.
- Take the Bat, Leave the Candy
- Thu, 24 Apr 2014 11:27:46 EDT - ‘Take me out to the ballgame’ doesn’t exactly conjure up images of apple slices and kale chips. The more likely culprits include French fries, soda and the occasional box of Crackerjacks. Unfortunately for children who play youth baseball, eating unhealthy food during practices and games may be contributing to weight problems, according to researchers.
- NASA aeronautics set to premiere high-flying sequel
- Thu, 24 Apr 2014 11:22:55 EDT - For the second time in as many years, NASA researchers beginning in early May will take to the skies with a DC-8 and other aircraft to conduct a series of flight tests designed to study the effects on emissions and contrail formation of burning alternative fuels in jet engines. This year's Alternative Fuel Effects on Contrails and Cruise Emissions flight tests, known as ACCESS II for short, will feature new science instruments and new flight profiles to follow.
- A step up for NASA’s robonaut: Ready for climbing legs
- Thu, 24 Apr 2014 11:20:27 EDT - Getting your "space legs" in Earth orbit has taken on new meaning for NASA's pioneering Robonaut program. Thanks to a successful launch of the SpaceX-3 flight of the Falcon 9/Dragon capsule on Friday, April 18, the lower limbs for Robonaut 2 (R2) are aboard the International Space Station (ISS). Safely tucked inside the Dragon resupply vehicle, R2's legs are to be attached by a station crew member to Robonaut's torso already on the orbiting outpost.
